Our Silica Gel Packets are incredibly useful for adsorbing moisture and prolonging the life of your belongings. You’ll easily be able to visibly see when the indicating gel beads are around 60 percent adsorbed when the orange beads turn dark green. When they’re dark green, you’ll know it’s time to consider replacing them with fresh silica gel packets. With our indicating packets, we only use orange indicator beads which are a safer alternative to the blue ones that contain Cobalt Chloride II. Silica gel desiccant is a non-flammable, and chemically inactive drying agent that adsorbs forty percent of its weight in moisture. Every single gel bead contains millions of surface pores that magically soak up water vapor. The beads adsorb moisture from humidity and create a protective environment of dry air that lengthens the life of your item. Therefore, it removes moisture from many locations and situations ranging from keeping items like shoes and books free from odors, to reviving your phone from a dreadful drop in water. They’re also excellent for preventing condensation so use them with guns and ammunition or with electronics like cameras. Protect your official documents and treasured photos with silica gel packets to ensure they will stay dry, despite how humid the storage area gets. All packets included are plastic packaged.
